The short answer is that it depends. “There isn't a ‘need’ for a humidifier for your baby,” explains Lauren Levine, M.D., a pediatrician affiliated with NewYork-Presbyterian/Columbia University Irving Medical Center and NewYork-Presbyterian Morgan Stanley Children's Hospital. But they can be helpful in certain climates and situations — the AAP suggests using a humidifier for baby if she has a cold, for example.
“Benefits for using a humidifier in the nursery include protecting your child's skin from drying out and decreasing nasal congestion by helping loosen mucus — especially helpful if he or she is having a cold,” says Luis E. Ortiz, M.D., a physician in the Sleep Center at Johns Hopkins All Children’s Hospital. “This can be a good thing, as there are limited over-the-counter remedies for children in this age group.” Moist air can also help ease coughing, adds Dr. Levine.
Humidifiers could also help keep skin moist if your child has eczema, and could help keep nosebleeds at bay, says Ellen M. Schumann, M.D., a clerkship director at the Medical College of Wisconsin.
When deciding whether your child's room needs a dehumidifier, you need to make sure that it doesn't make the room too humid or too dry.
"Children, especially young children, if the air is too dry, will produce mucus," says Punita Ponda, M.D., a New York-based Northwell Health physician who specializes in allergy and immunology and pediatrics. "You can't have it too warm, where it's too humid or too dry. So in a nursery, it's okay to have a dehumidifier, but you want to make sure it can regulate the humidity and it's not something that sucks humidity out of the air only."
